Diagnosis

Males of M. spinosa resemble those of M. mokana sp. nov. and M. ramirezi by sharing the same tibia I ventral spination, 4-4; they differ from those of the former mainly by having the spiniform AS II inserted on a large tubercle ( Fig. 8E ) (absent in M. mokana sp. nov.) and from those of the latter by the carapace lacking feathery setae (present in M. ramirezi ). Females resemble those of M. mokana and M. chickeringi by the absence of a spiniform AS II ( Figs 8B , 14B ), but differ by the presence of a thoracic groove and by the tibia I ventral spination being 5-5 or 6-6 ( Fig. 7D ) (thoracic groove absent and tibia I spination 4- 4 in both M. mokana and M. chickeringi ).
